The optical properties of lead formate crystals are investigated, especiall
y those affecting the usage for optical second-harmonic generation. The ref
ractive indexes and the optical absorption are measured in the near-ultravi
olet, visible, and near-infrared spectral regions. The data show that the m
aterial is suitable for the efficient generation of blue light when pumped
with near-infrared laser wavelengths. Phase matching conditions for this ap
plication of lead formate are determined both experimentally and by a numer
ical evaluation of the index data. (C) 2000 American Institute of Physics.
